After exposure to saltwater or heavy spray, rinse with fresh water and dry the exterior surface; avoid disassembling the instrument.
Usage recommendations
For best results in low light, allow your eyes a few moments to adapt and keep the exit pupils aligned with your eyes. Store the binoculars in a dry place when not in use and follow manufacturer guidelines for cleaning optical surfaces to preserve coatings and image clarity.
